Abstract
The sudden rise in chemical fertilizer prices has highlighted the need to focus on utilizing sewage sludge as fertilizer; however, consumer understanding is required as current utilization rates remain low. Consumer awareness regarding fertilizers differs across countries; thus, it is necessary to clarify consumer evaluations of sewage sludge fertilizers in Japan. This study’s survey results employ a price sensitivity measurement, showing that sewage sludge fertilizer is rated lower than other fertilizers, and evaluations differ depending on consumers’ knowledge. Thus, improving consumer understanding can increase demand. Furthermore, appropriate risk communication becomes an essential area for future study.
